The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the table for this stretch.

Right off the bat, it's a bit of a slow start. We've got a good long stretch of small, weak surf with us. The good news is that the water is sitting at 75°F right now, which is a solid 4°F warmer than usual for this time of year. That's a nice bonus if you're just getting in the water anyway.

For the first week and a half, we're looking at a lot of nothing. From Wednesday the 12th all the way through to late in the week of the 19th, the swell is tiny and the energy is just not there. The combined energy barely cracks triple digits on a couple of afternoons, sitting mostly in the 40s and 60s (64, 48, 44). The wind is mostly light, and we get a few glassy mornings on the 12th and 13th, but with waves only 1ft to 2ft, it's a flat spell. There's a bit of a bump on the 16th with a 5ft NW swell pushing the energy up to 245, but it's cross-on and messy, so I wouldn't get excited. That's a full week of waiting.

The first real standout comes on Thursday, August 20th. The swell starts to build, coming in from the NW at 4ft with a period of 11 seconds. That's a proper groundswell, and the energy is jumping to 439 – that's the first time we feel some real power. The wind is light and cross-shore, so it's clean but not perfect. The report calls it "marginal," but it's the best we've seen in a while. It's still a bit average for a beginner, as 4ft is pushing their limit.

Friday, August 21st is the pick of the whole forecast. The morning sees a 6ft NW swell, with a period of 9 seconds, and the energy is strong at 513. The wind is light and cross-offshore from the WNW, which is a clean wind for this spot. The conditions are expected to be good. The water is still warm, and the waves will have some punch. This is the one to circle on the calendar. It's a bit meaty for beginners, but for the more experienced crew, it's the best on offer.

The swell drops off quickly after that. Saturday the 22nd is back to small, and the rest of the run looks pretty ordinary. We get another glassy morning on the 25th with a 4ft NW swell, giving us an energy of 211, but it's a one-off. The last day of the forecast, Thursday, August 27th, shows a building 8ft NW swell in the afternoon, with a massive energy reading of 890. That's a lot of power, and it's a little too big for most; it's for experts only. The wind is cross-shore, so it might be a bit lumpy, but the size is undeniable.

So, to sum it up: wait for the 20th for a hint of something, but the real standout is the morning of Friday, August 21st. That's your window.

Information about the Karramarro Surf forecast

The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
